What’s the problem with the pH value in the pulp dyeing wastewater aeration tank dropping from 7 to 3?

If it can be reduced to 3, then it’s not a problem related to biochemical reactions; rather, it’s likely that production wastewater with a low pH value has been discharged into the tank. It is recommended to get in touch with the production workshop.

It definitely has nothing to do with the biochemical system; check the pH changes in the upstream water source.
